Abstract: A testable back pressure valve can include a housing comprising a housing body. The valve can also include a valve seat coupled to the housing, where the valve seat includes a valve seat body having a first cavity and a second cavity, and where the valve seat further includes a first network of channels disposed in the valve seat body. The valve can further include a valve head movably disposed within the first cavity of the valve seat. The valve can also include a piston follower movably disposed within the second cavity of the valve seat, where the valve head is fixedly coupled to the piston follower. The valve can further include a travel piston movably disposed within the second cavity of the valve seat, where the travel piston is moveably coupled to the piston follower.

Abstract: A method of transferring at least one subterranean core sample from a retrieval vessel to a testing vessel can include removing at least one pressure barrier on the retrieval vessel using a linear actuator while maintaining a sampling pressure on the at least one subterranean core sample at which the at least one subterranean core sample is taken from a subterranean formation. The method can also include pressurizing the testing vessel to the sampling pressure using the linear actuator, and transferring the at least one subterranean core sample from the retrieval vessel to the testing vessel. The method can further include sealing the testing vessel with the at least one subterranean core sample at the sampling pressure, where the testing vessel allows the at least one subterranean core sample to be tested while the at least one subterranean core sample is maintained at the sampling pressure.

Abstract: A subterranean coring assembly can include a body having at least one wall that forms a cavity, wherein the cavity has a top end and a bottom end. The subterranean coring assembly can also include a first flow regulating device movably disposed within the cavity, where the first flow regulating device is configured to move from a first default position to a first position within the cavity based on first flow characteristics of fluid that flows into the top end of the cavity toward the bottom end of the cavity.

Abstract: A downhole on-demand power source system can include at least one first energy storage device located within a wellbore disposed in a subterranean formation in a first inactive state. The system can also include at least one first trigger that initiates the at least one first energy storage device from the first inactive state to a first active state. The at least one first energy storage device, once initiated, can provide a first power to an electrical load disposed in the wellbore proximate to the at least one first energy storage device. The at least one first energy storage device, when in the first inactive state, is incapable of providing the first power.

Abstract: One embodiment of a method of performing a test on a core sample comprises transferring at least a portion of a core sample from a first core containment vessel to a second core containment vessel. The core sample is maintained at a substantially equivalent pressure or placed under a higher pressure during the transfer of the core sample from the first vessel to the second vessel. The method further comprises performing a test on the core sample in a measurement region of the second vessel.

Abstract: An artificial lift system utilizing a downhole impeller-style pump and a motor at the surface. The system includes a centralizer for use with the rod string or tubing. The centralizer centralizes a rotating rod at intermediate points within the tubing string. The centralizer includes a plurality of flexure springs and bearings. A rod string tensioner induces a tension load on the rod string.

Abstract: A testable back pressure valve can include a body. The valve can also include a first flow regulating device movably disposed within a top end of the body, where the first flow regulating device is configured to move from a first default position to a first position based on first flow characteristics of a first fluid that flows into a top end of the body toward a bottom end of the body. The valve can further include a second flow regulating device movably disposed within the bottom end of the body. The valve can also include a network of channels disposed within the body between the first flow regulating device and the second flow regulating device.
